Patch 707f853d7fa3 ("module: Provide EXPORT_SYMBOL_GPL_FOR_MODULES() helper")
from Peter was merged through Masahiro in v6.16-rc1. Since this is a related
fix/rename/cleanup, it'd make sense for it to go through his kbuild tree as
well. Masahiro, please let me know if you'd prefer otherwise. If not, I'll queue
it up in the modules tree.
